Boxcar Averager
The Zurich Instruments Boxcar Averager operates as a high-speed digitizer synchronized to a reference oscillator that is phase-locked to the periodicity of the experiment. In the case of the laser repetition rate, for example, every data sample recorded at the input can be associated with the phase of the experiment and the signal components not synchronized with the experiment are strongly suppressed. The implementation based on an external reference signal removes the trigger jitter, and the digital realization enables a dead-time-free operation.

Optical Chopper
These high stability variable frequency optical choppers each include a set of chemically blackened photoetched chopping discs. The mini chopper is an excellent choice for applications requiring a compact package. The chopping discs come in a variety of slot apertures and allow operation. Beam diameter is limited to 0.75mm when using the 200-slot disc and 1.0mm when using the 40 slot mini disc. The easy-to-interchange blades are made of non-magnetic, half hard brass and can be used in combination. Chopping frequency is set by adjusting a ten-turn dial or by applying an external DC voltage to the BNC input. Reference output is a TTL pulse and is in-phase with chopping action. The 5 digit led display gives a direct read-out of the chopping frequency. Power: 90-130V or 180-260V; 50/60Hz; 12VA max. Power supply included. Choppers are often used together with lock-in amplifiers.
